[Solved]-HighCharts - show last labels in xAxis-Highcharts

in addition to the showlastlabel property, you may need to add the endontick flag to your example. for example:

//...

xaxis: [{
    type: 'datetime',
    showlastlabel: true,
    endontick: true
},

//...

use tickpositions array:(number) to specifically identify which indices you want displayed on your xaxis.
